Breakout Text on Text-Table Gantt
This slide is nice because it organizes the descriptions for the milestones in a very efficient and readable way. Rather than placing the associated text next to the milestones, which clutters and maybe even obscures part of the chart, the breakout descriptions are neatly organized at the bottom of the slide with semitransparent leaders.
Additionally, the weeks are plotted by applying a fill color to the appropriate cells. This is also very efficient and easily editable.
